Representations of p-adic groups

These are the original notes written at the IAS
in June, 1974, with a major correction
suggested a couple of years later by Cartier
and a few other minor ones.
They were subsequently put into TEX
under Paul Sally's direction at the University of Chicago.
They contain a number of small mathematical errors.
The most egregious is the formulation of the Bruhat-Tits KTK reduction.
